The Phosphinoboration Reaction
The addition of boron–element bonds (where element = H, B, Sn, Si, Se, S) to organic substrates has become a fundamentally important reaction in organic synthesis over the past few decades. Classic examples are the hydroboration reaction (element = H) or diboration/borylation reactions (element = B), but many more reactions of this type are becoming an integral part of the arsenal of reactions available to organic chemists. Recently, the research group of Professor Stephen Westcott at Mount Allison University (New Brunswick, Canada) reported on a unique phosphinoboration reaction where compounds with a single P–B bond add readily to unsaturated bonds.
